ziiviiviERLI, DECEASED riLiNG SHELF Application iled September 11, 1928. Serial No. 305,165.

The present invention relates to detachable shelves and more particularly to one intended filing cabinet, desk or the like, an object thereof being to 'provide a device of this character which will facilitate the work of a ling clerk.

Another object of the invention is to provide a shelfso constructed as to be detachably supported upon'the side wall of'a drawer in such manner that papers to be filed, or as they are removed from the files, may be conveniently placed on the shelf without such member interfering with movement of the person doing the work.

. A further object of the invention is the provision 0f a simple and novel Vhinged bracket arm for securing and rigidly holding the shelf upon the vertical wall of a drawer an which will adapt itself to walls of different thickness.

In some instances the drawers of filing cabinets are provided with side rails which support the dra-wer on roller bearings, and it is a further object of the invention to so construct the rswinging bracket arm as to engage such side rails in a manner to securely hold the shelf in place ing itself to rails spaced different distances from the top of the wall.

And, a still further obj ect of the invention is the provision of a device of the character and for the purpose set forth which is of sim-V ple and strong construction, inexpensive to and so formed that a quantity of them may be nested so as to occupy but small space in shipment or storage.

To these ends the invention consists of a shelf construction as will be fully set forth in the following description and particularly defined in the appended claims.

The accompanying drawings illustra-ting the invention are as follows: p f

Figure l shows in perspective the shelf supported upon the drawer of a vertical filing cabinet. y

Fig. 2 is a plan view of the shelfand a fragmentary part of the drawer, a portion of the shelf being broken away.

Fig. 8 is a fragmentary plan view of theY the freedom of instead of directly'engaging the side wall, and with the arm adapts'` shelf frointhe under side with the bracket arin in itsinoperative position.

Figl is an enlarged sectional view as on the lined- 4, Fig. 2 butY showing a drawery without side rails.

Fig. 5 is a view spect to Fig. t. Y f i i Y find, Fig. 6 is a sectional detail on line c-e, Fig. 2. Y

In the drawings similar reference numerals refer to similar parts throughOut the several views.

` The numeral 1 represents a vertical fillingv from the right withre-` e cabinet an open drawer of which is shown at 2 and as including side walls 3 on which are rails d which support the drawer on roller hearings 5 mounted in eXtensible track ineml d bers 6. v y

"The present invention contemplatesa shelf adapted to be detachably supported upon either of the side walls 3 and having means,v

as a hinged bracket arm, on its under side for Vfrictionally engaging with a wedging action thewall of the drawer to'securely and rigidly hold the shelf in place and more firmly as the weight thereon is increased. l

The shelf is formed, preferably, from sheet meta-l in one piece and includes a horizontal portion Z and a vertical portion 8, the endk `edges of the horizontal Y downwardly to form reinforcing anges'9` and the outer side edge upwardly7 to provide aretaining flange 10 for papers placedl on the shelf.

On the under side of the horizontal portion or shelf proper is a hinged member which,

when swung into operative position, comprises a bracket arm l1 the free end of which has a contacting surface for frictionally engaging the outer face of the wall upon vwhich the shelf rests, this arm functioning to support the shelf and to hold the vertical por,-

Vtion 8 thereof in engagement with the inner face ofthe supporting wall. The shelf rests upon bend l2 which is-the junction of the horizontal and vertical portions 7 and 8, respectively, the inner ends of the flanges 9 being cut'back sufficiently to clear the drawer.

In this instance the bracket arm is a strip portion being turned the side wall of the drawer along the of sheet metal'having hinge connection with'a rod orpintle 14 secured to the under j facevof thehori'zontal portion 7 and at anY angle obliquely to the line of bend 12, the

ends of the rod being flattened and welded to washers 21v`wl1ich'in turn are similarlyl secured to the shelf, these washers preventing L pressible material, preferably. rubber, which theV pad being heldagainstdisplacement by lrod from the shelf soY 1 axial movement ofthe arm and spacing the that thek arm is vfree to swing. The -st'rip formingl'thearmhas an angularentension 15 whichv is turned backin spaced relation to the arm proper and with `its end 16 offset tolform an abutting surface which is spot welded to the,A arm. Thus the outer or free end of the arm 11 with its eX tension 15 forms a holder for apad.17 of comprojects beyond. theinner side edge vof Athe holder to providefa contacting surfacelS for yieldingly and frictionally engaging the outersurface of the wall s upporting Athe shelf,

` an abutting ear 19, bent from the arm 11.

abutting the innerfaeeof the wall. Y 1]. is'then swung downwardly past the vertii cal and upwardly until .the 4eontacting surfaceV 1S wedges against` thersupporting wall,

whereupon, such swinging member becomes an -angularly extend-ing v withvthe plane `of thearin inclined from the 40,

bracket arm, Y and,

vertical, av Wcdging action is'exerted which causes the friction 'surface'lS `to grip the wall 3 more firmly as weight upon the shelf `is in` ,creased. The relative arrangement of the.V

. pad 17 with .thearm 11 is such that after the f ace18 of the pad 1 7 Vsur ace 18 of the attachable, and by arm is swung past the vertical the contacting dially of the hinge, lies substantially `parallel with the wall, thus permitting the arm to accommodate itself to supporting walls of different thickness.

maximum gripping area to the wall 3 and, preferably, the pad is notched traversely at 20. to provide a two-point bearing which in` sures even greater relative, frictional engage,- ment between the walland the pad l17.`

side rail 4, as v1n Figs. A1, 2yand`6, the notched pad 17 after swinging to or beyond the vertical,.accordingto the width of the rail and its distance fromthe top of the drawer, will stra'ddleL the railuwhich"` acts'as a bearing for the free end Vof the bracketarm. -v Y The shelffitwill bepobservedp, is readily overhanging the side of Zontal portion,

' contacting surface pad, which is in a plagne-ra` The contacting edgeV is bevelledto present a In the' event the drawer is provided with a3 .Y mchned from the' Vertlcal' the drawerv will be so conveniently located as to greatly facilitate the work of filing. To remove the shelf it is simply raised from the drawerafter first swinging the arm 11 out of Vdisengagenient with the wall 3.

The-top edgeof a sheet metal drawer is usually reinforced by lhavingya portion turned back against itsouterface, as at 22,

FigQ4, and` itwill further be observed that the'angula-r arrangement of the hinge 'per` mits the'swinging arm to accommodate'itself to a wall thuspconstructed, tliat'is, the free or gripping end of the arm will swing clearof the reinforced edge 22 and contact with the thin body Aportion of the wall, which would' ,not be the case were the `armV hinged at right angles tothe wall of the drawer.
